1.44 Ct. Alexandrite from Tanzania

This alexandrite is a transparent, pear shape gem weighing 1.44 carats, with dimensions of 8.43 by 5.96 by 3.85 millimeters, a mixed brilliant cut, and an excellent polish. The weight alone is a primary determinant of this stone s rarity and value within the alexandrite market, because natural color changing stones in this size range are uncommon. At 1.44 carats this specimen crosses a frequently noted threshold where per carat prices increase substantially, because collectors and high end jewelers prize larger, intact crystal material that displays a clear color change and good clarity. The combination of shape and cut translates the weight into a strong face up presence, the pear outline maximizing the apparent size while the mixed brilliant facet design concentrates light return and color play across the table. The stone s proportions are well balanced, with a depth of 3.85 millimeters that yields a depth ratio of approximately fifty three percent relative to the average of its length and width, a proportion that supports both optimal brilliance and an attractive face up area for its carat weight.

The optical character of this alexandrite is defined by its bluish green to reddish purple color change, a defining attribute that further amplifies value when coupled with natural, untreated material. The gem s color intensity is described as medium, a range that preserves the distinct shift between daylight and incandescent conditions while maintaining clarity and transparency. Clarity is graded as slightly included when evaluated at eye level, and those minor internal features do not materially detract from the gem s overall brilliance or durability, particularly given the excellent polish and precise facet intersections of the mixed brilliant cut. Importantly, there has been no enhancement to alter color or clarity, which is a strong value driver for alexandrite, because untreated color change is significantly more desirable to both connoisseurs and investors than modified material. Origin is Tanzania, and Tanzanian alexandrite occupies an important place in the global supply, producing material that can combine pleasing color change with attractive clarity, while remaining far less common than many commercial gem species, thereby contributing to the stone s collectability and market interest.

From a practical and valuation perspective, the 1.44 carat weight positions this alexandrite as a versatile and high value center stone for bespoke jewelry. In a pear shape there are established setting strategies that preserve the gem s optical qualities and protect the pointed termination, and the gem s measurements make it suitable for a solitaire ring or an elegant pendant where the color change can be appreciated in varied lighting. Weight is a compounding factor in alexandrite pricing, because as size increases the scarcity of comparable quality material rises faster than linear, creating a premium for stones at and above this carat level. The mixed brilliant cut and excellent polish optimize light performance and color dynamics, which in turn supports a higher per carat valuation than a comparable weight in a less well cut or treated specimen. When assessing total value one must consider the interplay between weight, color change intensity, clarity, polish, cut proportions, absence of treatment, and documented origin, all of which are favorable in this piece.

The Natural Gemstone Company presents this alexandrite as an example of a naturally occurring, untreated color change gem with a weight and set of attributes that make it both rare and desirable. For buyers and appraisers evaluating alexandrite, the combination of a 1.44 carat weight, transparent material, distinct bluish green to reddish purple color change, slightly included clarity at eye level, excellent polish, and Tanzanian origin represents a well balanced profile that supports both aesthetic and investment considerations.
